I tried to profile ASP.NET application in IIS loaded with 10 jmeter threads and the profiler freezes and the application is not serving any request after 2 mins of profiling.Profiling same application loaded by 50 jmeter thread on WebDev server of VS2010 was fine.I noticed that it freezes even without sampling, freezes with sampling too.When sampling was running I can take a snapshot of couple of minutes of data before the freezing. But is is not enough. The application cycle is much larger than 2 minutes.
